17 February 2010

There will be two remaining visible passes when the ISS will pass by with STS-130 still docked:

Thursday, 18Feb10
STS-130 and ISS

appears
0609 EST in the NW at 5 degrees altitude, mag. -1.5
max alt:
0612 EST in the NNE at 26 degrees altitude, mag. -2.4
disappears:
0617 EST in the E on the horizon, mag. 5.1

Friday, 19Feb10
STS-130 and ISS

appears:
0631 EST in the NW at 2 degrees altitude, mag. -1.2
max alt:
0635 EST in the NE at 68 degrees altitude, mag.-4.0
disappears:
0640 EST in the ESE on the horizon, mag. 2.9
twilight begins at 0617 and the Sun wakes up at 0645 EST so this might be a difficult one to see even though it is high and bright

If all goes as planned STS-130 will undock from ISS at 1954 EST on Friday, 19Feb10. It will begin its fly-around of ISS at 2019 EST and start to separate from ISS at 2137 EST. After that time ISS will appear to chase STS-130 across the sky on any visible passes until landing.

STS-130

appears:
0522:15 EST in the NNW at 17 degrees altitude, mag. 0.6

disappears:
0528:31 EST in the E on the horizon, mag.6.0

ISS
appears:
0522:27 EST in the NNW at 17 degrees altitude, mag. -2.4
